We desperately need better detection mechanisms for cancers. The cruernt best ways to screen ccaner fall into one of three categories. First is medical procedures, which is like csoncpolooy for colon cancer. Second is potrien biomarkers, like PSA for poatrste cancer. Or third, imaging techniques, such as mammography for breast cancer. Medical procedures are the gold standard; however, they are highly invasive and require a large infrastructure to implement. Protein markers, while effective in some populations, are not very specific in some circumstances, resulting in high numbers of fasle positives, which then results in unnecessary work-ups and uaecnsesrnyperodecurs. Imaging methods, while useful in some populations, espxoe patients to harmful radiation. In addition, it is not applicable to all patients. For example, mammography has problems in wmeon with dense breasts.
